Many star names are, in origin, descriptive of the part in the constellation they are found in; thus Phecda, a corruption of Arabic فخذ الدب ( fakhdh ad-dubb, 'thigh of the bear'). Only a handful of the brightest stars have individual proper names not depending on their asterism; so Sirius ('the scorcher'), Antares ('rival of Ares ', i.e ...
Of several items, then called radio stars, Cygnus A was identified with a distant galaxy, being the first of many radio stars to become a radio galaxy. [25] [26] First quasar: 3C273: Virgo: 1962 3C273 was the first quasar with its redshift determined, and by some considered the first quasar. 3C48: Triangulum: 1960
Below are lists of the largest stars currently known, ordered by radius and separated into categories by galaxy. The unit of measurement used is the radius of the Sun (approximately 695,700 km; 432,300 mi). [1] The Sun, the orbit of Earth, Jupiter, and Neptune, compared to four stars.
BPM 37093 — a diamond star. Cygnus X-1 — X-ray source. EBLM J0555-57Ab — is one of the smallest stars ever discovered. GY Andromedae — chemically peculiar variable star. MACS J1149 Lensed Star 1 (or Icarus) — second most distant star, 9 billion light years away.
Lists of galaxies. Look up galaxy in Wiktionary, the free dictionary. A galaxy is a system of stars, stellar remnants, interstellar gas, dust, dark matter, bound together by gravity. The word is derived from the Greek galaxias, literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.
A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity. [ 1 ][ 2 ] The word is derived from the Greek galaxias ( γαλαξίας ), literally 'milky', a reference to the Milky Way galaxy that contains the Solar System.
The Sun is the brightest star as viewed from Earth, at −26.78 mag. The second brightest is Sirius at −1.46 mag. For comparison, the brightest non-stellar objects in the Solar System have maximum brightnesses of: the Moon −12.7 mag [1] Venus −4.92 mag. Jupiter −2.94 mag. Mars −2.94 mag.
A few notable large stars with masses less than 60 M☉ are shown in the table below for the purpose of comparison, ending with the Sun, which is very close, but would otherwise be too small to be included in the list. At present, all the listed stars are naked-eye visible and relatively nearby. Star name. Location.
